BOSTON (AP) — A company with the same founders as a specialty pharmacy tied to a deadly meningitis outbreak has agreed to extend its voluntary closure until Nov. 19.

Ameridose shut down for inspection Oct. 10 amid an outbreak linked to a tainted steroid made by the New England Compounding Center. Ameridose and NECC have the same founders, Barry Cadden and Greg Conigliaro, though Cadden has since resigned from Ameridose.

Westborough-based Ameridose had been scheduled to reopen Monday. But on Friday, the state Board of Registration in Pharmacy asked to extend the closure another two weeks.

In a letter, the board cited Ameridose’s voluntary recall of all its products this week after federal inspectors said the company must improve its sterility testing process. No infections have been linked to Ameridose products.

The fungal meningitis outbreak has killed 29.
